The video shows the Feyenoord hooligans in black, and those from AZ arranged in white. On the battle cry of “Feyenoord Hooligans!” the groups then charge at each other.

The lines quickly descend into a chaotic melee, with punches and kicks flying in all directions.

There is even a ‘referee’ in a high-vis jacket and the combatants wear MMA gloves and mouth guards to minimise injury.

The scrap was an example of a phenomenon known as 20-20 fights, where 20 combatants on each side battle according to a clearly defined set of rules, which normally excludes the use of any weapons and hitting or kicking those already fallen to the ground.

The dangers of football-related violence was laid bare this week when shocking footage showing the moment a man was pushed in front of a Tube train by a mindless England fan in revenge for ‘Russian footie hooligan attacks at Euro 2016’ emerged.

A 32-year-old man from west London was sentenced to 10 years in prison for the unprovoked assault, after the court heard his victim could feel the electricity coursing through him and hear a train.

The new video, in which the Feyenoord hooligans seemingly got the upper hand against those from AZ, follows a video which surfaced last November in which a group of Feyenoord hooligans got a beating from French outfit Nancy.

The Nancy fans apparently had an old score to settle from 2006, when crowd troubles during Nancy’s 3-0 UEFA Cup win over the Rotterdam outfit saw the Dutch side being thrown out of the tournament.

The group stage game had to be abandoned for half an hour because of the crowd disturbances as Feyenoord hooligans tried to smash the glass barriers and threw seats at stewards.
